Clinical history and CT were suggestive of a venous malformation with phleboliths. Excision biopsy was performed. Histopathology revealed intravascular papillary endothelial hyperplasia with fibrotic-calcific changes. Hypoesthesia in the supra-orbital region persisted postoperatively. Although a benign lesion, intravascular papillary endothelial hyperplasia should be considered a differential diagnosis of a vascular lesion with compressive effects.en© 2010 The American Society of Opthalmic Plastic and Reconstructive Surgery, Inc.EyelidsOrbitEndothelium, VascularHumansHemangioendotheliomaEyelid NeoplasmsHypesthesiaHemorrhageHyperplasiaDiagnosis, DifferentialTomography, X-Ray ComputedMiddle AgedFemaleJournal article002009599310.1097/IOP.0b013e3181b8e0e90002761293000152-s2.0-7794998234635377Selva-Nayagam, D.
